I keep getting the error message below when I try to convert a fitted pipeline to a PMML file.

CalledProcessError Traceback (most recent call last)

I have no idea what is going on, because your error report doesn't contain any information about the underlying Java exception.

This Java exception is printed to the console, right above the Python traceback information. It should start with java.lang.IllegalArgumentException (or something very similar), followed by ten or more lines that start with at:.
